Chiller Fluids, Anti Freeze & Heat Transfer Fluid. ComStar's ProFrost (Propylene Glycol) and Frost Free (Ethylene Glycol) are premium industrial coolants that can be ordered with/or without a color and with/or without a corrosion inhibitor package designed to prevent system corrosion and clog-ups.

Common tap water is slightly acid that can eventually corrode metal system components. In addition, water may contain minerals that may contribute to the build up of lime/scale deposits that can reduce heat transfer and clog pipes. Because glycols without a corrosion package are more corrosive than water it is strongly recommended to order glycols with the corrosion inhibitor package. Lastly, never use automobile anti-freeze in a non-automotive application. Automotive anti-freeze contain inhibitors that tend to react and coat heat exchange surfaces, thereby reducing energy efficiency.
